[movies]The Helix Nebula
A 3-D model of the Helix Nebula shows a structure much more complex than suspected. The Helix Nebula is a planetary nebula, created when gas is expelled by a dying, Sun-sized star. The star becomes a white dwarf -- look for it in the center of the Helix.Find out more on HubbleSite: http://hubblesite.org/newscenter/archive/releases/2004/32/

*Description*: The top composite image is a view of the colorful Helix Nebula taken with the Advanced Camera for Surveys aboard NASA's Hubble Space Telescope and the Cerro Tololo Inter-American Observatory in Chile. The object is so large that both telescopes were needed to capture a complete view. The Helix resembles a simple doughnut as seen from Earth. But looks can be deceiving. The bottom illustration shows how the Helix would appear if viewed from the side...

[movies]Iridescent Glory of Nearby Planetary Nebula Showcased on Astronomy Day - *Credit:* NASA [ http://www.nasa.gov/ ], NOAO, ESA [ http://spacetelescope.org/ ], the Hubble Helix Nebula Team, M. Meixner (STScI [ http://www.stsci.edu/ ]), and T.A. Rector (NRAO).
*Description*: This cropped version of the Helix Nebula mosaic shows cometary-filaments embedded along a portion of the inner rim of the nebula's red and blue gas ring. At a distance of 650 light-years, the Helix is one of the nearest planetary nebulae to Earth. The composite picture is a seamless blend of ultra-sharp NASA Hubble Space Telescope (HST) Advanced Camera for Surveys images combined with the wide view of the Mosaic Camera on the National Science Foundation's 0.9-meter telescope at Ki...
